INTRAVASCULAR STENT WITH EXPANDABLE COATING |
摘要 |
An intravascular stent (26) has a surface coated with a biocompatible layer. The layer contains a diamond like nanocomposite material. This nanocomposite material comprises carbon, hydrogen, silicon and oxygen as constituent elements. The layer has a stress which is less than 150 MPa in order to ensure a high degree of flexibility and a complete expandability. This lower stress is obtained by the inclusion of relatively large amounts of Si:O bonds. In a preferable embodiment the layer with diamond like nanocomposite material covers the stent (26) for 100%. This is obtained by allowing the stent to move freely along a wire during CAVD deposition. |
